There is no telling the amount of time he will miss with the second one.

The Chargers left tackle exited Sunday's 24-6 win over the Jaguars with his second concussion in a month, a scary recurrence from a Sept. 22 one against the Titans. Left tackle Mike Remmers briefly filled in during the first quarter before being carted off on the first play of the second quarter with a high ankle sprain.

Right tackle D.J. Fluker finished the game at left tackle, playing near the full final three quarters.

“It got better as it went along,” Fluker said.

San Diego has maintained success despite the fluidity on quarterback Philip Rivers' blind side. Fluker was the fifth different Charger to play left tackle in the past three weeks; Michael Harris, Nick Becton, Remmers and Dunlap are the others.

This is the third documented concussion of Dunlap's NFL career. He had one in 2011, coming in Philadelphia against the Cardinals. He missed three games.

“Anytime a teammate gets hurt, it's just hard for everybody,” center Nick Hardwick said. “It's mostly hard for him. It's hard for his family. We just wish him a speedy recovery; come back and join the party.”

Dunlap was seen in the locker room after the win, interacting and laughing with teammates. Players concussed are not available to media until they are medically cleared to resume football activities.

The timetable of any concussion is taken on a case-by-case basis. He will continue to be evaluated this week.
